Convert mov to lea for loading address of local common symbol
There is no need to check def_regular when converting mov to lea for loading address of local symbols since def_regular may be false for common symbols and SYMBOL_REFERENCES_LOCAL is sufficient. bfd/ * elf32-i386.c (elf_i386_convert_mov_to_lea): Don't check def_regular. * elf64-x86-64.c (elf_x86_64_convert_mov_to_lea): Likewise. ld/testsuite/ * ld-i386/lea1.s: Add a test for loading address of local common symbol. * ld-x86-64/lea1.s: Likewise. * ld-i386/lea1a.d: Updated. * ld-i386/lea1b.d: Likewise. * ld-i386/lea1c.d: Likewise. * ld-x86-64/lea1a.d: Likewise. * ld-x86-64/lea1b.d: Likewise. * ld-x86-64/lea1c.d: Likewise. * ld-x86-64/lea1d.d: Likewise. * ld-x86-64/lea1e.d: Likewise. * ld-x86-64/lea1f.d: Likewise.
